I have been using a zeis conquest 4.5 x 14 rapid z 8oo this hunting season. I love it. Very fast and accurate if you know your muzzle velocity and use the zeis website to optimize the various holdover bars. The glass is very clear. I suggest testing the scope set at your optimized power to make sure the wind bars work for your caliber. Personally, I prefer to dial the scope, but out to a reasonable distance of 500 -600 yds or so, this scope is very fast.
I will be changing all of my hunting rifles to this scope as time and money permits.
